The 3M Speedglas G5-01 Welding Helmet is designed to protect welders in heavy duty welding conditions (200-400 Amp). The typical working environment for this type of welding means a lot of heat, radiation (UV and IR), light, sparks, spatter, high speed particles and of course welding fume.
Respiratory Protection in Australia and New Zealand
In Australia, respirators are rated based on a Required Minimum Protection Factor (RMPF) in Australian Standard AS/NZS1716. This indicates, if properly worn, the level to which the respirator protects the wearer from the surrounding pollutants. Powered Air Purifying Respirators if correctly worn have a RMPF of 50 meaning that they supply air a minimum 50 times cleaner than the welder would otherwise be breathing unprotected. There is no higher level of protection attainable for powered air respirators in Australia or New Zealand.
Global Respiratory Ratings
However, in the US and parts of Latin America, the APF 1000 performance level for respirators is used and is the highest possible classification. This classification has a higher performance level than the RMPF classification used in Australia and the TH3 classification used in Europe. The Speedglas G5-01 when used with the shroud and large head cover has achieved this APF 1000 rating. Therefore the G5-01, if correctly worn, supplies air a minimum of 1,000 times cleaner than the welder would otherwise be breathing unprotected.
To put this into perspective, that’s ONE HUNDRED times cleaner air than the welder would breathe through a fit tested disposable respirator or reusable half-face respirator. This rating has never been achieved in a Speedglas Powered Air Respiratory Welding Helmet and has changed the game in the protection of welders against carcinogenic welding fume.
G5-01: the ultimate in protection, comfort and adaptability
This higher level of respiratory protection, combined with climate control inside the welding helmet, gives welders a new level of respiratory comfort and protection. With a welding helmet solution that not only provides the right level of protection, but also increases the comfort of the targeted welders in this environment, the 3M Speedglas G5-01 provides a solution that is more likely to be both used and liked by welders.
